When using weldments to make a frame using aluminum extrusions, such as Bosch or 80/20, is there a way to get the end treatments to stop at the outermost face of the mating extrusion? In 2009 and 2010, it keeps wanting to extrude the end of one body into the t-slot of the mating frame piece. This is using either End Butt 1 or End Butt 2 Trim/Extend. It doesn't matter if I use the checkboxes for allow extension or the selections for simple/coped cut. It seems like the simple/coped cut choice should result in the right behavior, but it does not. The result of this is that we wind up with wrong lengths in the cut-list.
